Hi, I did a search on changing the stock Automatic transmission system to a sportshift, tiptronic AT one; it seems that the 'levelten' company is making one (or is it finished already?) If it's finished, anyone has the result and price on that?

One more question, I have a MY01 RS 4EAT. I know the transmission will engage in 90/10 split after the 2nd gear, and there is a way to modify it and lock it on 50/50 all the time. Does anyone know how to do that? And since there are comments said about changing to 50/50 will damage the tires and/or AWD system in the long run, would it make our 4EAT cars slower on corners?
